My 22 caliber Air Venturi Avenger, is losing air at the rate of about 200 PSI every 24 hours. It used to hold air for weeks and months without losing anything.

I guess I'll start here,

Does anybody have any advice on the most common place to have leaks? Should I brush on some soapy water and look for bubbles?

Thanks for any advice or experiences.
